Romney's opposition means both of the last two Republican
presidential candidates — Romney and Sen. John McCain (R-AZ) —
have both come out publicly to urge Brewer to veto. Romney is on
the board of directors of Marriott, which
sent a letter to Brewer Monday calling on her to veto the
bill.

"Governor Brewer hasn’t yet made a decision," the Brewer
spokesperson said in an email to Business Insider
Tuesday. "The Senate transmitted its bill to
our office yesterday while the Governor was in DC. When she
returns, she will take the time necessary to thoroughly review
and evaluate the legislation before taking
action."

Brewer has until Friday to sign the bill into law or
veto it. She also could simply do nothing, in which case the bill
would still become law. In Washington on Monday for National
Governors Association meetings, Brewer told CNN that she
would "do the right thing for
Arizona."
